X = soft tacos
y = double deckers

Dory:
3x + 3y = 11.25 

Nemo:
4x + 2y = 10.00

---Now to solve for x and y---
---We find LCM of either x or y then make them cancel each other---
Dory multiply by 2:
6x + 6y = 22.50

Nemo multiply by 3:
12x + 6y = 30.00

--eliminate y--- 
Nemo subtract Dory:
6x = 7.50
Therefore x = 7.50 <em />÷ 6 = 1.25
---Now substitute x = 1.25 in either equation.---

Dory:
3.75 + 3y = 11.25
Therefore 3y = 11.25 - 3.75
therefore 3y = 7.50
there fore y = 2.50

y = 2.50 , x = 1.25

Sorry, that this is so long, I hope you understand. This is called simultaneous equations, you can read up on it.

Please answer if you know the answer!<br><br> [Help]
Alinara [238K]

Remember that an exponent means repeated multiplication.

The exponent of 4 means you have four \big(b^2\big)'s mutiplied together:

      \big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)\cdot\big(b^2\big)

And then each exponent of 2 inside means you have two b's multiplied inside each set of parentheses.:  

    \big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)\cdot\big(b\cdot b\big)

There are 8 b's there when you expand this out.

P=175e^-0.090times 25
zysi [14]

Here's my interpretation of your equation:


P=175e^(-0.090*25) (not P=175e^-0.090times 25 )


Then P = 175(0.105) = 18.4, or approx 18.
